What are the values?Which of the two years has the higher variance? What are the values?Based on the statistical output, would you conclude that variances are equal or not equal? Provide an appropriate/authoritative explanation leveraging the statistical output.2.Run an appropriate t-test (assuming either equal or unequal variances based on your conclusion in 1c above) using an alpha level of 0.05and answer the following questions:Is this a one-tailed or two-tailed test?
